RESILIENT WHEEL-TIRE AND ADJUSTABLE RIM.

Application filed December 10, 1917.

To (IZZ whom it may come-m Be it known that; I. l 'nAXK ll. TURNER, a citizen of the United States. residing at ()cala. in the county of Marion and State of Florida, have invented. certain new and useful Improvements in Resilient Wheel- Tires and Adjustable Rims, of which the following is a specification.

This invention relates to tires for automobile and other vehicles and has for its object to provide a comparatively simple and inexpensive device of this character including means whereby the wheel rim may be adjusted to apply lateral pressure on the tire casing and the resilient element therein.

The invention consists in certain novel features of construction, as hereinafter shown and described and then specifically pointed out in the claim; and in the drawings illus trativo of the preferred embodiment of the invention- Figure l is a side elevation of a portion of an automobile wheel with the improvement, applied, the tire casing and the adjustable rim being in longitudinal section.

lfig. 2 is an enlarged sectional View on the line 2-2 of Fig. 1.

Fig. 3 is an enlarged sectional detail of the resilient tiller member of the tire casing.

Fig. 4 is an enlarged plan view of a portion oi the adjustable rim.

Fig. 5 is a section on the line 5-5 of Fig. l.

The improved device 1s designed to replace the ordinary cxpausible inner tube of an automobile wheel, and occupies the space of the inner tube. The improved attachment may be of any required size to adapt it to tire casings of various sizes, and is formed initially of a single strip of material represented as a hole at 10 having the edges chamtered or beveled as indicated at 11 in Fig. 23, and then wound in spiral form with the beveled edges in relatively close relation as illustrated in Fig. l. The ribbon of sheet metal is curved to conform to the curvature of the casin represented as a Whole at 12,

0 n I n and dlsposed therein before the casing is Specification of Letters Patent.

while the other section It is provided with a plurality of lips 20 adapted to engage in the slots and thus couple the sections 13-14t together. The slots 19 are arranged in groups transversely of the rim sections,-so that the tongues or projections 20 may be inserted in the slots to enable the rim sections to be adjusted laterally of the tire and thus tighten the tire casing upon the spiral core member, as will be obvious. By this means the rim may be readily adjusted to correspond to the size of the tire, and apply the requisite pressure against the spiral core, and hold it firmly in position.

By forming the metal ribbon with its edges chamt'ered or beveled no sharp edges are projected against the inner wall of the casing, hence the wear and friction upon the casing is rendered negligible. The material of the casing is thus from the metal strip.

Having thus described the invention, what is claimed as new is:

The combination with a tire rising, of a resilient core disposed within the casing and means for coi'npressing the walls of the tire casing against the core, said means comprising a rim including coat-ting annular sections having their inner edges overlapped, one of the rim sections being provided with a plurality of transverse rows of spaced apertures and the other with tongues adapted to enter the apertures.

In testimony whereof lt alfix my signature.
